According to a report from TomsHardware, Seagate said last week that its hard drives using heat-assisted magnetic recording (HAMR) technology began shipping as early as November last year, and it has expanded its shipments of Mach.2 technology hard drives that use dual drives. Seagate believes that this combination of technologies can increase capacity and improve hard drive performance in the next few years.
For the current mechanical hard disk, increasing the hard disk capacity is very important, but while the capacity, track density, and linear read/write speed increase, the random read/write IOPS performance per TB has decreased. Such performance will affect The operation of the data center. In order to increase the sequential read/write speed and increase the IOPS performance per TB, the hard disk manufacturer has developed a hard disk with two independent drives on the shaft, which is effectively placed in a 3.5-inch hard disk. Seagate is the first hard drive manufacturer (at the end of 2017) to launch multi-drive technology (MAT). In 2019, it began to conduct sample tests on this hard drive (Exos 2X14) with selected customers.
It is understood that customer interest in dual-drive hard drives has increased significantly, so Seagate has decided to expand the evaluation program and increase shipments of this type of hard drive. However, it is not clear when Seagate plans to sell dual-drive hard drives to the retail market. At present, the demand for large-capacity hard drives in data centers is increasing. Last summer, Seagate began shipping nine 18TB hard drives. Once customers are qualified, they will soon increase shipments.
As part of the Seagate Live storage system, HAMR technology hard drives have been provided to specific customers, and HAMR technology hard drives will be more widely available to users in the future. Seagate expects HAMR technology to increase the capacity of hard drives at an average annual growth rate of 20%, which means that 24TB hard drives will soon arrive.
